The config.yml file at the root of your repository is the configuration file you’ll use to define three entities, specified as the following top-level keys:
  1. databases: database connections
  2. models: foundation model connections
A sample config.yml file is shown below: 
databases:
  - name: primary-database
    type: bigquery
    key_path: /path/to/keyfile
    dataset: dataset-name
  - name: local
    type: duckdb
    key_path: None
    dataset: /path/to/local/files

models:
  - name: openai-4.1-mini
    vendor: openai
    model_ref: gpt-4.1-mini
    key_var: OPENAI_API_KEY
  - name: llama3.2
    vendor: ollama
    model_ref: llama3.2:latest
    api_url: http://localhost:11434/v1
    api_key: secret

Environment Variables

You can use environment variables for database connection parameters instead of hardcoding values. This is recommended for production deployments and keeping sensitive data out of version control. For example: 
databases:
  - name: postgres_prod
    type: postgres
    host_var: POSTGRES_HOST
    user_var: POSTGRES_USER
    password_var: POSTGRES_PASSWORD
    database_var: POSTGRES_DATABASE
See the Environment Variables Reference for complete documentation.
